Summary of Diagnosis of disease
The video discusses the relationship between concepts in healthcare and the nature of disease, focusing on physiology, pathophysiology, clinical features, etiology, signs, symptoms, history, observations, investigations, interventions, and evaluation.
Key Points
- physiology refers to normal function and structure, while pathophysiology is abnormal function that gives rise to clinical features.
- etiology, the study of causality, can be genetic, environmental, or epigenetic factors that cause alterations in physiology leading to pathophysiological changes.
- clinical features can be signs (physical observations) or symptoms (patient-reported), and can be assessed through history, observations, and investigations.
- Investigations can include hematological, biochemical, microbiological, and imaging studies to aid in diagnosis and treatment planning.
- Interventions should be evidence-based and evaluated for effectiveness, leading to a cyclic process of assessment, planning, implementation, and evaluation.
- The goal is to correct pathophysiological changes and restore normal physiology in patients, managing ongoing limitations when necessary.
- Understanding healthcare involves grasping the relationships between concepts and being able to interpret the arrows connecting them.

Notable Quotes
— 00:56 — « Physiology can change to pathophysiology and pathophysiology is abnormal function now thats bad because we dont want the body to function abnormally but its good because it gives us an opportunity to work out what is going on because pathophysiology will give rise to clinical features. »
— 01:53 — « As healthcare providers, we need to be able to recognize and interpret clinical features, deducing from that that pathophysiological and indeed specific pathophysiological changes have taken place. »
— 04:12 — « So there can be observations and also we can get information from investigations, we can investigate our patients, we might order ultrasound to see whats going on or different forms of radiology. »
— 04:58 — « You can tap, these are the classic methods of investigation of clinical signs: observation, auscultation, palpation, and percussion. »
— 06:30 — « Tied into that also informing about the clinical features is the history, so we talk to the patient to get histories of the clinical features. »
